UNITED STATES PATENT OFFICE.

CHARLES W. PIERCE, OE OAK HILL, NEW YORK.

DOOR-LATCH.

SPECIFICATION forming part of Letters Patent No. 293,512, dated February12, 1884.

' Application filed June 23, 1881. Renewed October 4, 1883. (No model.)

To Cl/ZZ whom, it may concern:

Be it known that I, CHARLES W. PIEROE, of Oak Hill, Greene county, NewYork, have invented a new and useful Improvement in Door-Latches, ofwhich the following is a specification.

My invention consists ofimproved contrivances in the construction of theguard for the latch 5 also, of the catch,whereby the method of fasteningthem to their places issimplified and cheapened, and the number ofscrews therefor lessened.

Figure l in the accompanying drawings is a side elevation of adoor-latch and the catch therefor, constructed accordingtomy invention.Fig. 2 is an elevation taken at right angles to that of Fig. 1. Fig. 3is a side ele- 'vation of the'latch-bar alone.

A representsthe latch; B, the guard therefor; O, the drop-lever camforlocking the latch; D, the catch; and E,the wearing-plate behind thelatch, to prevent the rubbing of the latch against the door. r

Heretofore the guard B and the wearing-plate E have been attached to thedoor by two screwsone at the top and the other. at the bottom, above andbelow the latch, the one at the top serving for the pivot for thedrop-bar fastener Oand two screws have also been em ployed to fasten thecatch D to its place. Now, I propose to cast the guard B with a stud, F,at each end in the place where the fastening-screws have heretofore beenlocated, said studs being adapted to pass through theholes of thewearing-plate E, same as before made for the screws, and enter the woodsufficiently to prevent the guard and plate from shifting out of theirproper position, and employ a single screw, H, in connection therewith,to fasten them to the door,--the said screw being located in the middle,or thereabout, between the studs and passing through a slot, J, which Iprovide in the latch, to allow it to rise and fall, as required. Theupper stud is also adapted for, and serves the purposes of, the pivotfor the drop-fastener, same as the screw now used. As in the oldarrangement, I make the necessary shoulders or projections, I, on one orboth parts,to adj ust and maintain the guard I the proper distance awayfrom the plate for fastening this part of the latch. By substantiallythe same arrangement of two studs K and one screw L, I economize-in thecost of material and labor for the application of the catch D,which Imake double, in connection with this mode of attaching that is, with anotch, M, on both the upper and lower sides-in order that it may,together with this kind of fastening, be reversible. The single catchfastened by two screws is reversible simply by having the screw-holescountersunk on both sides; but with these studs it is necessary toreverse the sides, and hence, together with them, I make the catchdouble-notched.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s

In a door-latch, the guard B, having the studs F extending through theplate E and into the door, in combination with the latch A, having aslot located under or behind said guard, and with an attaching-screw, H,located between said studs and passing through said slot in the latch,substantially as described.-
